I've been installing the Dual Pro PS4 with excellent results (+10pcs).
I did have one unit which required a warranty service. They faxed me a UPS label, and the unit was repaired and returned quickly.
Had I not clipped off a corner to fit it in the boat, they offered to send me an exchange outright.
The PS4 is not designed to operate as a power supply off a genny, and will overheat if overtaxed.
The LED display correctly identified a weak AGM battery, which was replaced without incident. Very handy.
Downsides: The unit is unwieldy to mount, as it relies on old school transformer technology. On the other hand, it can work off a 15a 100vac supply. Some of those remote slips get some pretty droopy power, but the Dual Pro auto-corrects with the heavy transformer. Worth the install effort. Order the hair extenders if the supplied 4ft battery leads won't reach. The original battery wires cannot be extended practically, as they have thermistors in the rubber blocks for battery temperature sensing.
Be Well,
Arby

Subject: [Electric Boats] QUAD BATTERY CHARGERS FOR A 48 VOLT BANK
I'm about to start my third season with electric propulsion and plan to order a quad type battery charger in addition to the 48 volt Zivan NG-1 charger already installed. I'm doing this to hopefully keep the four 210 amp AGM batteries in the bank in a better balanced state when charging rather than just using the Zivan which sits across the entire bank. I'm also hoping I can use this second charger along with the Zivan to add a few more amps to the controller when motoring and hence more speed without depleting the battery bank. But, the primary purpose will be to balance the battery bank. I'm considering two quad chargers 1) Is a Dual Pro 2) The second is a Genius I'm leaning toward the Dual Pro unit because it seems to have more LED indicators as to the charge condition of the battery. But, any comments or any other choices in quad chargers would be welcome. Capt. Mike |
